3T-GTEU mods?

[tbag]

yer few questions dnt kno much bout this engine. want to upgrade power output. already decided on ditching the ct20 turb an goin 4 a t3/t4 setup.an running a link. obviously once this is done im goin to nd to run bigger injectors. some stuf id like to know if anyone can help is... Is it worth me changin to custom plenum an fuel rail and porting inlet and/or exhaust ports? Ive heard oil pressure is a problem when doin these mods? eng wil be goin back in my TE71 corolla mated to W55 an disc rear end.
